西瓜小丑
[xī guā xiăo chŏu]
Watermelon Clown can imply two things; first, it refers to the red part of a watermelon looking like a clown's makeup when sliced, second, it also represents a humorous personality who brings joy and laughter as both are enjoyable in different forms. But be aware that this might have derogatory implications when used out of context among friends.
